Meet Me at the Corner

This Meet Me at the Corner activity & project also includes:

Geometers use their knowledge of vertical, alternate interior, and corresponding angles in a real-world activity. Engineers plan to install guard rails at dangerous intersections of a city and need to know the angle at which to construct the rails. Students use a map of the city and work in groups to find various angle measures formed by intersecting streets. They even write a proof to convince the engineers that their measurements are correct. The resource includes follow-up questions and two good extension activities.
